WATERPROOFING PASTE.

1N0 Drawing. Application filed September This invention relates generally to the art of water-proofing materials, and particularly to such materials as leather, imitation leather and certain kinds of fabrics which it is desired to make impervious to moisture.

The first object of this invention is to provide an exceedingly simple and eiiicient water-proofing paste which can be easily applied and Which will effectually seal open-' ings one-thirty second of an inch in diam-' eter in fabrics without any tendency of stiffening the fabric so treated, or causing its structure to deteriorate in any manner.

The second object is to so combine a number of ingredients as to secure not only the advantage of their well known properties taken separately, but the increased advantage of combining them in the manner about to be described for this particular purpose, with the result that a highly improved form of water-proofing composition is obtained thereby.

These objects are accomplished by preparing the composition as follows: To one gallon of boiled linseed oil is added one pint of turpentine; then separately'to one pound of Burgundy pitch is' added one pound of yellow beeswax. The wax and the pitch are. heated and stirred to'thoroughly melt and unite the ingredients. The linseed oil and turpentine 1s warmed and the melted pitch and Wax is added thereto and thoroughly stirred. The liquid is then poured into tins or other. containers for use or shipment.

In applying the composition to porous materials such as leather, canvas or imitation leathers such as are used on automobile tops, etc. it isonly necessary toapply the material to the surface of the object being 40 treated by means of a suitable brpsh or soft cloth, rubbing same well into the surface of the material and allowing same to set for, preferably twenty-four hours, although in some instances. of course, this time can be much reduced, as, for example, when applying same to leather boots and shoes, or when the atmospheric conditions are such as to increase the rate of evaporation.

Obviously, theexact amount of the vari- 5e ous ingredients employed can be varied considerably without departing from the spirit of this invention, but itmust be understood that all of the above-mentioned ingredients must be employed if it is desired to secure 55 any resemblance to the properties of this preparation. i

It must also be understood that the amount applied to the fabric, as well as the brushing in operation, can be varied con- 60 siderably, depending upon the nature of the article being treated.

I claim:

A water-proofing paste consisting of approximately one gallon of boiled linseed oil, 65 one pint of turpentine, one pound of Burgundy pitch and one pound of yellow-becswax.
